CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 550,015, dated November19, 1895.

Application filed April 4, 1892. Serial No. 427,659. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM F. F. BUCK, a citizen of the United States,residing at Kelso, in the county of Sibley and State of Minnesota, haveinvented certain new and useful Improvements in Corn-Planters; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to a novel construction in corn-planters, theobjects being to provide adevice of this character of improved andefficient construction that is adapted to automatically drop the corninto the furrow, cover the same, and to mark at the end of a row justplanted the points where the corn has been dropped, so as to determinethe place of planting the corn in the next row.

To these and other useful ends my invention consists in the features ofconstruction and combinations of parts hereinafter fully described andspecifically claimed.

In the accompanying drawings, illustrating my invention, Figure 1 is atop plan view of the corn-planter constructed in accordance with myinvention. Fig. 2 is a longitudinal vertical section of the same, takenon the line 2 2 o f Fig. 1. Fig. 3 is a side elevation and partly insection on the line 3 3 of Fig. 1. Fig. 4 is a vertical transversesection taken on the line 4 4 of Fig. 1. Figs. 5 to 12, both inclusive,illustrate detail views.

Referring to said drawings, A A indicate tWo longitudinal beamscomposing the main frame of the device. Said beams are connectedtogether at their rear ends by cross-pieces 1, and near the forward endsthereof are located three cross-supports 2, 3, and 4, the said supports2 and 3 being located a little in advance of the middle of the beams,While cross-support 4 is located at the forward ends thereof. Thesecross-supports are all secured rigidly to the said beams and extend onboth sides thereof to about the width of the corn-planter.

The corn-planter is supported at its rear portion by the wheels 5 and 6,one of said wheels being rigidly secured to the axle or shaft 7, that issupported in bearings 8, secured to the beams A A', while the otherwheel may be secured to said shaft by a pawl and ratchet. The saidwheels 5 and 6 are of the ordinary construction, embracing a wideconcave tire that is employedto close or cover up the furrow inthe usualmanner. A rockshaft a is mounted upon the rear end of the beams A A andis provided at its outer ends with scraping-plates h, that are adaptedto be thrown against the concave tires of the wheels to remove the dirttherefrom. A vibrating foot-piece c, that is located in position to beoperated by the driver from the seat d, is connected by means of the rode with an arm f upon said rock-shaft a, so that the scrapingplates canbe thrown against the wheels at will.

The runners 9 are secured to the forward end of the machine and just infront of each of the wheels 5 and 6 and, like the ordinary corn-planter,serve to open a furrow for the dropping of the corn, the rear end ofsaid runners 9 being bifurcated in the usual manner. Above said rear endof the runners and supported upon the cross-supports 2 and 3 are locatedthe seed-boxes B.

In accordance with my invention the seed device is adapted for plantingeither corn or 'various other seeds, such as squash, and the seed-boxesB are therefore divided into two compartments by transverse partition10.

The forward compartment 11, which is larger than the rear compartment12, is adapted to receive the corn, and a tube 13 leads fr om saidcompartment 11 to the rear end of the runners 9,while a small tube 14leads from the compartment 12 to said runners.

The device for feeding the corn into the tube 13 consists of areciprocating slide 15, that moves back and forth, and is located in thebottom of the said compartment 12 between said bottom and theguide-piece or cut-off 16 secured therein and extending over the upperend of the tube 13. An opening 17 is made in the slide 15 and normallystands away from said tube 13 and from under the guide 16, so that thecorn or other seed can fall into the said opening 17, as shown in Fig.3. It will thus be noted that when the slide 15 is moved forward thecorn that is in the opening 17 will be carried forward and dropped intothe tube, while the guide 16 will prevent more corn from falling thereinuntil the slide returns to the position shown in said Fig. 3. I

IOO

have provided means for adjusting the size of the openin g 17, wherebythe amount of corn to be dropped each time can be regulated. To this enda movable piece 1S is located within the opening 17, and is providedwith a slotted stem 19, and is secured within a longitudinal recess inthe slide l5. It will thus be seen that by reason of the slottedconnection between the movable piece 1S and slide 15 the said movablepiece can be moved back or forth and enlarge or decrease the size of theopening 17.

rlhe slide 15 extends beneath the partition and is provided wit-h anopening 20, that is normally located within the compartment 12 of theseed-boxes. Just at the forward end of said compartment the upper end ofthe tube 14 communicates with the same, so that when the slide 15 ismoved forward any seed that may be held within the opening thereof willbe allowed to drop in said tube. It will be noted that when the slide isat the forward limit of its movement part of the opening 20 will belocated in compartment 1l,and to cover such part a plate 2l is securedwithin the lower rear portion of compartment l1 for such purpose.

I will now proceed to describe the devices and means whereby theseed-dropping mechanism is operated automatically during the advancementof the corn-planter.

Upon the axle 7 of the wheels is located a sliding collar 22, that isprovided with a sprocket-wheel The said collar is provided at one endwith clutchteeth that are adapted to be engaged by the clutch-teeth of astationary collar 24, so that when the two are in engagement with eachother said collar 22 and sprocket-wheel will revolve with the axle 7.The devices for throwing said collar into and out of gear with theclutch colla-r 24 comprise the cam-surfaces 25, that are secured to arock-shaft 26 upon the beams A and A', Figs. 1, 2, 5, and 6. Thesecamsurfaces are rigidly secured to said rockshaft 2e', andan arm 27 islocated between said cam-surfaces 25 and is loosely mounted upon saidrock-shaft. The other end of said arm 27 is forked and engages anannular groove 2S upon the collar 22 of the axle 7. To one end of saidrock-shaft 26 is rigidly secured a notched plate 29, and a lever 30 isloosely mounted upon said rock-shaft and is provided with a pawl 31,located to engage said notched plate 2 5). It will thus be seen that byconnecting the lever 30 with said notched plate 2.() the rock-shaft canbe moved by swinging said lever, and thus the collar 22 can be throwninto or out of engagement with the clutch-collar 24 for obvious reasons.About midway between the ends of the beams A A a shaft 32 is supportedin bearings upon said beams. The said shaft is provided with asprocket-wheel 34, and a sprocketchain 35 is trained around saidsprocketwheel 34 and the sprocket-wheel 23 of the axle 7, so that whenthe rear sprocket-wheel `49 is pivoted an armed wheel 50.

is being driven by the axle a rotary motion will be imparted to theshaft 32 through the intermediacy of the gear connection between suchparts. The shaft 32 is provided with crank-ar1n 3G, that is connected bymeans el' a pitman 37 with a longitudinal. sliding bar 38, confined byguideways 39 upon the crosssuppor 's 2 and 4 of the frame of themachine.

lt will of course be understood that an internilittent motion must begiven to the slide 15 of the seed-boxes that the forward movement ofsaid slide should be gradual, while it should be returned quickly andsuddenly to its normal position, as shown in Fig. 3.

To accomplish the above-named objects in a simple, efficient, andcertain manner, I have constructed the devices which will now bedescribed.

The forward end of the slide 115 isconneeted by means of the link 40with an upwardlyprojecting arm 4l upon the rock-shaft 42. Saidrock-shaft 42 is mounted in bearings at its ends upon side supports45),that extend between the ends of the cross-supports 3 and 4. The saidside supports 423 are vertically slotted, and another arm 44 is securedto said rock-shaft 42 and extends down tlnough the slotted portion ofthe said side support 43 and will more fullybe explained hereinafter.Adjacent the beam A the said rock-shaft 42 is provided with adownwardly-projecting arm 45, that is pivotally connected by a link 4Gwith one end of an arm 47, that is rigidly secured upon an upright shaft48, supported in bearin upon the beam A and cross-support 3, Figs. l, 2,and S. The up per end of said upright shaft 4S is provided with twohorizontal arms 49, that extend toward the sliding bar 3S, heretoforereferred to, and between the outer ends el' said arms The pivot of saidarmed wheel extends below the lower arm 4f) and is provided with aratchet-wheel 51, that is engaged by a spri1'1g-pawl 52, Fig. S. Thesaid teeth of the ratchet-wheel are so arranged that the armed wheelwill only be permitted to turn to the right, or, in other words, thearms of the said armed wheel are only permitted to move to the rear onthe side ad jacent the bar 38.

The slides 15 of the boxes and the connecting parts above described areall held normally in the relative positions they will assume when theslide is at the backward limit of its movement, and this is accomplishedby a spring 53, that is connected with the projection on the upper sideof the rock-shaft 42, and with the cross-support 3, located in the rearthereof. The action of said spring 53 turns the rock-shaft 42 in itsbearings and draws the slide 15 back in an obvious manner, while at thesame time the link 4G and arm 47 will be moved to the forward limit oftheir movement, and the upright shaft and arms 49 on the upper endthereof' will be moved accordingly. The reciprocating motion of the bar3S serves to move the arm 49 IOO intermittently, whereby the slide 15 ofthe feed-boxes will be moved forward and then returned by the action ofthe spring 53. This occurs while the machine is moving forward and thesprocket-wheel 28 turns with the axle. It will be understood, of course,that various devices could be employed for communicating theintermittent motion to the arms 49; but as a convenient and preferableconstruction I have secured to said bar 38 an uprising projection 54,that is provided at its forward end with an upright antifrietion-roller55, located to engage one of the arms of the armed wheel 50. It will benoted that as the bar 38 moves forward the said antifriction roller 55will engage the rear edge thereof, Fig. 1, and during the forwardmovement of the said bar and the antifrietionroller the arm 49 will bemoved forward owing to the pawl-and-ratchet connection between saidarmed wheel and arm 49. In Fig. 1l is shown in full and dotted lines thedifferent positions these parts may assume during their several moments.c. When they bar 38 is moved forward far enough, the arm of the armedwheel that engages the antifriction-roller will at last be released'therefrom and also from the spring-pressed movable antifriction-roller56 in the rear thereof. The spring 53 will return the rock-shaft andarmed wheel and connected parts to their normal condition. (Shown inFig. 1.) The forward movement of the armed wheel moves the slide 15until the opening therein is located over the tube 13, so that the cornwill drop through said tube into the furrow made by the runner. When thearmed wheel is released, the parts will quickly return to their normalposition by means of the spring 53. The bar 38 then commences to returnor move backward by meansof its crank connection with the shaft 32, andthe movable projective antifrietionroller 56, Fig. 10, iirst strikes theprojecting arm of said armed wheel, which it will move to the rear, (byreason of the pawl-and-ratchet connection of said armed wheel with thearm 49,) and when the said arm of the armed wheel that was formerlylocated in the path of the antifriction-roller of the bar 38 is movedback almost forty-five degrees the spring action of saidantifriction-roller 56 will force it laterally until it stands inlongitudinal alignment with the machine. This has the effect of bringinganother arm of the armed wheel in position to be engaged by theantifriction-roller 55 at the next forward movement of the bar 38, itbeing noted, Fig. 9, that the ratchet-wheel 51 of said armed wheel isprovided with four teeth. In Fig. lO is shown in detail the constructionof` said movable antifriction-roller 56, which comprises a frame 57, inwhich said roller 56 is mounted, said frame 57 being located within therecess 58 in the projection 54 and provided with a stem 59, that passesthrough an opening in the rear end of said recess 58. A spring 60 islocated within the recess and 'presses against the rear end of saidframe 57 and forces the same laterally. The pin 61 passing through saidstem 59 prevents the frame from passing out of said recess. To thedownwardly-projecting arm 44 of said rock-shaft 42, heretofore referredto, is connected the slotted end of the link 62, and said link 62 passesrearwardly and is pivotally connected with the upper end of a lever 63,that is pivoted upon the frame of the machine. The rear end of saidlever 63 passes through a slot 64 in the forward wall of the tube 13 andis pivoted to a follower 65. It will be seen by the foregoingdescription that as the rock-shaft turns in its bearings the saidfollower 65 will be raised or lowered intermittently by reason of theslotted connection between said arm 44 and the link 62. Thisintermittent motion of the follower 65 serves to prevent the corn orseed from clogging or stopping within the tube 13v in an obvious manner.

It will be plainly obvious from the foregoing description that when thecorri-planter is traveling lacross vthe fieldY the parts .can be thrownintoposition to plant' the corn continuou'sly and when the machinearrives near the endof the row it is necessary to mark the points atwhich the corn has been dropped, so that afterV the machine is turnedaround the iirst hills of the next row can be planted inalignment'therewith in the usual manner; and to accomplish this purposeI have arranged two hoes 66, that are adaptedto mark the ground at thepoint where the corn is dropped. Of course during the planting of therow it is unnecessary to have these hoes operated, and the mechanismoperating them is only thrown into gear at the end of the row. The saidhoes are connected by arm 67 with theV rock-shaft 68 and supported inbearings on the beams of the machine and provided at one side,preferably the left-hand side, with an upwardly-projecting arm 69. Saidarm 69 is pivotally connected with a sliding rod 70, Fig. 12, whichpasses through bearings in the cross-supports 2 and 3, and is providedat its rear end with an upwardly-projecting lug 71.A This lug 71 ispivoted to a sliding rod 72, which latter is pivoted to another slidingrod 73, and the said sliding rod 73 is pivoted at its rear end to an arm74 upon the rock-shaft 75 by a foot-lever 76, that is located inposition to be operated by the driver of the machine. A spring 77 isconnected at its forward end with the cross-support 3 and at its rearend with the lug 71 of the sliding bar and serves to hold said vslidingbar 70 at the forward limit of its movement, so as to hold the hoes outof the ground, and it will be noted that by oscillating the foot-lever76 through the intermediacy of the several sliding bars the hoes can bethrown down into the ground at any point. This construction affords ameans whereby the driver can mark the points at which the corn has beendropped when the seeddropping mechanism is in gear with the axle of themachine, as will be more ICO IIO

lsegment 7 8 upon said shaft 32.

fully described hereinafter. The mechanism for operating said hoes whensaid machine is operated by the axle is constructed as follow The shaft32 extends beyond its bearings upon the beam A and is provided with atoothed segment 7S, while the sliding rod 7 2, that is locatedimmediately under said segment 7 8, is provided with a toothed portion79. Vhen the parts are in the position shown in Figs. 2 and 12, the saidsegment 78 will not engage the toothed portion 7 9 of the rod 72; but Ihave provided means for lifting said rod 72, so that its toothed portionwill be engaged at every revolution of said segment, so that the rod 72will be moved backward to throw the hoes down into the earth. The devicefor raising said rod 72 consists of an upright S0, having its lower partpassing through a vertical opening S1 in the beam A', Fig. 7 andprovided with a projection S2, through which the rod 72 slides. Anupright guide S3 passes through saidprojection 82 and serves to confinethe vertical movement of the upright 80. The upper portion of saidupright S0 is toothed, as shown at Si, and is located to be engaged bythe pinion 85, carried by a revoluble shaft S6, that is supported inbear ings S7 on the frame of the machine, and is provided with a handle8S, located in position to be operated by the driver. It will thus beseen that by turning the shaft 86 the upright S0 will be elevated, whichwill in turn elevate the sliding rod 7 2 to bring the toothed portionthereon in position to be engaged by the The said handle SS is providedwith a pawl 89, that engages the toothed portion 90 upon one of thebearings 87, by means of which the shaft 86 can be held in its adjustedposition.

It will thus be seen from the foregoing description that when themachine arrives near the end of the row the driver can, by throwing thesliding rod 72 into gear with the revolving segment, operate said hoes00 so that the latter will be thrown into the ground every time that thecorn is dropped,it bein g intended that such parts are so constructedand arranged with relation to each other that the downward movement ofsaid hoes will occur just as the corn drops. The segment only moves therod 7 2 sufficient to throw the hoes down and then leaves the same,whereupon the spring 77 will lift said hoes until they are again actedupon by the said segmeut.

At or near the end of the row it may be sometimes necessary to throw theseed-dropping mechanism out of gear when itis desired to drop more cornbefore the machine is turned for another row, and in this case it isnecessary to have mechanism that can be operated by the driver to dropthe seed and also tomnark the point at which it has been dropped. Toaccomplish this purpose, the end of the revoluble shaft 86 is providedwith a beveled gear-pinion 91, and a bevel gear-pinion 92 upon the shaft32 is located to be engaged by said bevel gear-pinion 91. The shaft SGis located in sliding bearings, and a spring 93 is arranged upon saidshaft and serves to hold it at the rearward limit of its movement withthe gear-pinions out of engagement with each other, and when the shaftis in this position the pinion engages the toothed portion 8l with theupright 80. Vhen it is desired to operate the corn-dropping mechanism bythis shaft 86,the said shaft is pushed forward until the bevel gear-pinions 91 and 92 intermesh with each other, whereupon said shaft is turnedso as to turn, the shaft 32 and operate said corn dropping mechanism inan obvious manner. At the same time, by means of the oscillatingfootlever 76, the hoes 66 can be operated to mark the point at which theseed drops.

To the rear end of the machine, Figs. 1, 2, and 3, is secured a markerC, said marker being mounted at the end of a rod 94;, which rod ispivoted toa projection 95, that is itself journaled in a cross-piece 1of the frame of the machine. The length of the rod 94C is sufiicient tohold the marker out far enough to mark the next row in which the machinemust travel, and the marker is held by means of a rope or strand 9G,secured thereto at its rear end and connected at its forward end to thetongue D of the machine. In this way it will be seen that the marker canbe turned from one side of the machine to the other in an easy manner.The tongue D is pivotally mounted upon a pivot-pin 97, that is supportedn bearings projecting from the beams of the frame, and an adjustableplate 98 is secured to the cross-support et of the frame that pressesagainst the upper end of the said tongue. Said plate is slotted and canbe adjustably secured to said cross-support, whereby the elevation ofthe runner can be regulated. means of the pivotal connection between thetongue D and the frame of the machine it will be noted that the saidrunners will easily ride over any projection or unevenness of theground.

The rear end of the tongue D is provided with a toothed segment 99, thatengages a toothed segment 100, secured to a rock-shaft 101, whichrocleshaft is provided with an upwardly-projecting arm 102, that isconnected by means of a rod 103 with the lever 30, said lever 30 beingprovided with a spring-pawl 104, that engagesa toothed segment 105 uponthe beam A of the machine. It will thus be seen that by reason of thetoothed segments 99 and 100 the runners 9 can be raised off the groundand held in this position by the engagement of the spring-pawl 10i withthe segment 105 of the beam A.
